IMPROVEMENT IN WRITING-DESKS FOR CHAIRS.

Specification forming part of Letters Patent No. 162,097, dated April13, 1875; application filed April 8, 1875.

To all whom it may concern:

Be it known that we, JAMES A. PARK, of Lansing, and WILLIAM WoonHoUsE,of Mason, both in the county of Ingham and State of Michigan, haveinvented certain new and useful Improvements in Writing-Desks forChairs; and we do hereby declare the following to be a full, clear, andexact description thereof, reference being had to the accompanyin gdrawing, and to the letters of reference marked thereon.

Our invention relates to that class of writingdesks which are attachedto chairs; and the nature of our invention consists in the constructionand arrangement of the desk, and also in the devicesfor supporting andadjustably connecting the same to a chair, as will be hereinafter morefully set forth.

In order to en. others skilled in the art to which our inve fi timppertains to make and use the same, we will now proceed to describeits construction and operation, referring to the annexed drawings, whichform a part of this specification, and in which- Figure 1 is aperspective view of a chair with our writing-desk attached thereto. Fig.2 is a perspective View of the desk and fastening device attached, andFig. 3 is a perspective view of the paper-holder.

The desk is made in the form of a box, A, of any suitable form anddimensions, divided in the interior into compartments for holding paper,pens, and other articles, as required. The top of the desk-box A isformed of a stationary part, B, at the outer end, and a hinged lid, 0,at the inner end. The stationary part B may be covered with oil-cloth orother suitable material, as commonly used on desks. On the side of thedesk is a suitable projection, with strap or other device forpermanently attaching an inkstand, E. In the desk, immediatelyunderneath the stationary top B, slides a paper-holder, consisting of aboard, D, with a clip at its outer end. The clip consists simply of amolding, G, with thumbpiece a formed thereon. The outer edge as of themolding may either sit in a groove made in a bar or cleat, I), attachedto the board D, or may be hinged to the board. The inner edge of theclip is provided with a metal edge,

(I, which will hold the paper when torn off, and act as a cuttertherefor, and the clip is held down by means of rubber bands or rubbersprings c e, as shown in Fig. 3. At the inner rear corner of the desk isfastened a curved metal arm, H, provided with a series of perforations,y y, as shown in Fig. 2. Along the inner edge of the desk, at the rearend, is hinged a triangular brace, I, provided at its rear edge with twovertical points or pivots, h h, one at the top and the other at thebottom, and on a straight line with each other. On the side of the chairto which the desk is to be attached is fastened a casting, J,constructed in any suitable manner to fit the chair, and formed with twoholes or sockets, M, on a straight line with each other, into which thepins or pivots h h are inserted. The casting J is further provided witha pin, m, upon which the arm H is placed by the pin passing througheither of the perforations y therein. By this means the desk may beadjusted at any angle desired, and it is held by means of a brace, L,connected to the outer edge of the desk, and having its lower endnotched and placed in the lower angle of the brace I.

The desk thus constructed and held will be sufficiently steady for allpractical purposes. It may be adjusted at any angle desired, and whennot in use can be folded in over the ohair,or can be entirely lifted offand hung up in any convenient place out of the way.

The paper-holder, by sliding in the desk, allows the writer to move hispaper up as the writing progresses, and dispenses with the moving of thearm and hand.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is-

1. A desk divided into compartments, and provided with a connectingdevice folding therewith, whereby it can be attached to a chair,substantially as set forth.

2. In a desk attachment for chairs, thedeskbox A, divided into suitablecompartments, and provided with the hinged top 0, stationary top B, andsliding paper-holder D G, substantially as and for the purposes hereinset forth.

3. The combination of the perforated arm H, hinged brace I, providedwith the pivots h h, and a casting, J, provided with the holes orsockets 11 i and pin m, substantially as and for the purposes herein setforth.

4. The combination, with a desk, A B C, of the perforated arm H, hingedbrace I, provided with the pivots h h, and a casting, J, attaohed to achair, and provided with the holes or sockets z i and pin m, and abrace, L, for

supporting the desk, substantially as and for the purposes herein setforth.

In testimony that we claim the foregoing as our own we have heretoaffixed our signatures in presence of two subscribing witnesses.
